注册

1. 后端接口设计：

请求方式： POST /users/

请求参数： JSON 或 表单

返回数据： JSON

{
    "id": 9,
    "username": "python8",
    "mobile": "18512345678",
}

视图原型

# url(r'^users/$', views.UserView.as_view()),
class UserView(CreateAPIView):
    """
    用户注册
    传入参数：
        username, password, password2, sms_code, mobile, allow
    """
    pass

2. 后端实现

在users/serializers.py中创建序列化器对象

class CreateUserSerializer(serializers.ModelSerializer):
    """
    创建用户序列化器
    """
    password2 = serializers.CharField(label='确认密码', write_only=True)
    sms_code = serializers.CharField(label='短信验证码', write_only=True)
    allow = serializers.CharField(label='同意协议', write_only=True)

    class Meta:
        model = User
        fields = ('id', 'username', 'password', 'password2', 'sms_code', 'mobile', 'allow')
        extra_kwargs = {
            'username': {
                'min_length': 5,
                'max_length': 20,
                'error_messages': {
                    'min_length': '仅允许5-20个字符的用户名',
                    'max_length': '仅允许5-20个字符的用户名',
                }
            },
            'password': {
                'write_only': True,
                'min_length': 8,
                'max_length': 20,
                'error_messages': {
                    'min_length': '仅允许8-20个字符的密码',
                    'max_length': '仅允许8-20个字符的密码',
                }
            }
        }

    def validate_mobile(self, value):
        """验证手机号"""
        if not re.match(r'^1[3-9]\d{9}$', value):
            raise serializers.ValidationError('手机号格式错误')
        return value

    def validate_allow(self, value):
        """检验用户是否同意协议"""
        if value != 'true':
            raise serializers.ValidationError('请同意用户协议')
        return value

    def validate(self, data):
        # 判断两次密码
        if data['password'] != data['password2']:
            raise serializers.ValidationError('两次密码不一致')

        # 判断短信验证码
        redis_conn = get_redis_connection('verify_codes')
        mobile = data['mobile']
        real_sms_code = redis_conn.get('sms_%s' % mobile)
        if real_sms_code is None:
            raise serializers.ValidationError('无效的短信验证码')
        if data['sms_code'] != real_sms_code.decode():
            raise serializers.ValidationError('短信验证码错误')

        return data

    def create(self, validated_data):
        """
        创建用户
        """
        # 移除数据库模型类中不存在的属性
        del validated_data['password2']
        del validated_data['sms_code']
        del validated_data['allow']
        user = super().create(validated_data)

        # 调用django的认证系统加密密码
        user.set_password(validated_data['password'])
        user.save()

        return user

在users/views.py中定义视图

class UserView(CreateAPIView):
    """
    用户注册
    """
    serializer_class = serializers.CreateUserSerializer

3. 前端编写

修改js/register.js

        // 注册
        on_submit: function(){
            this.check_username();
            this.check_pwd();
            this.check_cpwd();
            this.check_phone();
            this.check_sms_code();
            this.check_allow();

            if(this.error_name == false && this.error_password == false && this.error_check_password == false 
                && this.error_phone == false && this.error_sms_code == false && this.error_allow == false) {
                axios.post(this.host + '/users/', {
                        username: this.username,
                        password: this.password,
                        password2: this.password2,
                        mobile: this.mobile,
                        sms_code: this.sms_code,
                        allow: this.allow.toString()
                    }, {
                        responseType: 'json'
                    })
                    .then(response => {
                        location.href = '/index.html';    
                    })
                    .catch(error=> {
                        if (error.response.status == 400) {
                            if ('non_field_errors' in error.response.data) {
                                this.error_sms_code_message = error.response.data.non_field_errors[0];
                            } else {
                                this.error_sms_code_message = '数据有误';
                            }
                            this.error_sms_code = true;
                        } else {
                            console.log(error.response.data);
                        }
                    })
            }
        }
